Thaum pib ntawm lub xyoo tom ntej, AMD npaj yuav qhia thawj Ryzen 4000 series processors - mobile hybrid chips ntawm Renoir tsev neeg. Thiab yog tias txhua yam ntau dua lossis tsawg dua nrog cov txheej txheem processor - cov chips yuav muaj Zen 2 cores, tom qab ntawd nrog cov duab sib xyaw ua ke txhua yam tsis meej. Txawm li cas los xij, tam sim no cov ntsiab lus tau tshwm sim hauv Is Taws Nem hais txog cov duab sib xyaw ua ke uas APUs yav tom ntej yuav tau txais. Thiab tam sim ntawd cia peb nco ntsoov tias qhov no yuav yog cov duab nrog Vega architecture.
Ib qhov chaw paub zoo ntawm kev xau hauv qab lub npe Komachi tau tshaj tawm cov npe ntawm cov txheej txheem los ntawm tsev neeg Renoir, suav nrog Ryzen 5, Ryzen 7 thiab txawm tias Ryzen 9 chips, nrog rau ntau tus qauv Ryzen Pro series. Nws tau xav tias cov npe B10, B12 thiab cov zoo li qhia txog kev teeb tsa ntawm cov duab sib xyaw ntawm cov chips no. Ntawd yog, tus lej ntawm no qhia txog tus lej ntawm Compute Units (CUs) ntawm cov duab sib xyaw. Piv txwv li, Ryzen 9 nrog "B12" cov duab xav tias muaj 12 CUs.
B12 = 12 CU.
つまり、Renoir “Mobile” APUのiGPUは12CUですか.— 比屋定さんの戯れ言 @ Komachi (@KOMACHI_ENSAKA)
Nco ntsoov tias tam sim no AMD hybrid processors muaj qhov siab tshaj plaws ntawm 11 suav nrog ntawm cov duab sib xyaw. Qhov nce ntawm cov CUs nyob rau tiam tom ntej yuav tau yooj yim los ntawm kev hloov mus rau 7-nm txheej txheem thev naus laus zis. Qhov no tseem tuaj yeem pab ua kom lub moos ceev ntawm cov duab sib xyaw ua ke thaum tswj kev siv hluav taws xob tsawg, uas yog qhov tseem ceeb tshaj plaws rau cov txheej txheem txawb.
Kuj tseem muaj cov lus qhia uas ntxiv rau Vega 12, peb yuav pom ntau dua "built-ins". Raws li tau sau tseg los ntawm lub khoos phis tawj nyiam nrog lub npe hu ua Locuza, yog tias AMD tso tawm cov duab sib xyaw ua ke Vega 13, tom qab ntawd qhov tshwm sim ntawm Vega 15 yog ua tau. Qhov khoom yog tias hauv Vega architecture, rau txhua 32 KB ntawm kev qhia cache (L$) thiab 16. KB ntawm qhov cache tas li (K $) tuaj yeem suav txog txog peb CUs. Raws li qhov tshwm sim, peb tuaj yeem tau txais txog li 12 (4 × 3) lossis txog li 15 (5 × 3) cov lej suav.
Tau kawg, tag nrho cov ntaub ntawv hais saum toj no tsuas yog lus xaiv nyob rau lub sijhawm no. Txawm li cas los xij, yog tias nws hloov mus ua qhov tseeb, tom qab ntawd nyob rau tiam tom ntej ntawm AMD hybrid processors peb yuav rov tau txais kev koom ua ke ntawm Vega graphics (GCN5), thiab AMD yuav siv cov Navi niaj hnub (RDNA) ntau dua hauv kev sib xyaw GPUs tom qab. Txawm li cas los xij, kev tsim khoom yuav tsum tau nce ntxiv. Yog tias AMD siv txawm tias 12 CUs thiab nce ntau zaus, tom qab ntawd cov duab ntawm Renoir processors yuav muaj peev xwm ntseeg siab tshaj qhov "built-in" Intel Iris Plus G7 hauv Ice Lake chips, thiab nrog 15 CUs nws tuaj yeem kov yeej cov duab tsis sib xws. ntawm GeForce MX250 qib.
